Prescription for Oxygen

Oxygen is a drug and a physician must write a prescription for oxygen therapy. The prescription will spell out the flow rate, how much oxygen you need per minute - referred to as liters per minute (LPM or L/M) - and when you need to use oxygen. Some people use oxygen therapy only while exercising, others only while sleeping, and still others need oxygen continuously.
